George Parris III, Capital One In many companies, the cornerstone of their continuous integration and continuous deployment strategy is a few, well known pieces of automation software that are absolutely vital to the way companies are building software these days using agile methodologies. Many times though, someone with some infrastructure experience will just spin up a server and install the packages, building and iterating upon that same install for the following years that they're using it, which puts them in a shaky place every time they have to make changes to it. On the Online Account Opening project at Capital One, we’ve strived to maintain our entire infrastructure as immutable as possible. In doing so, it was decided that we should apply that principle to our core CI/CD automation tools as well. By using Config As Code, Implementing a useful backup and testing strategy, and utilizing some AWS capabilities, we’re able to make that happen.
